Diabetic Retinopathy01:27

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Area of Science:

  • Ophthalmology
  • Retinal Diseases
  • Medical Imaging

Background:

  • Diabetic retinopathy (DR) severely affects visual function, often before irreversible visual acuity loss.
  • Accurate functional tests are crucial for diagnosing and monitoring diabetic patients, especially those treated for diabetic macular edema (DME).
  • Evaluating the visual function safety of DME therapies is essential.

Purpose of the Study:

  • To highlight the importance of functional tests in managing diabetic retinopathy.
  • To introduce microperimetry as a key tool for assessing retinal sensitivity in DME patients.
  • To emphasize the role of microperimetry in the evolving approach to functional investigation of DR.

Main Methods:

  • Utilizing microperimetry for fundus-related quantification of retinal sensitivity.
  • Applying functional tests for diagnosing and following diabetic patients with DME.
  • Investigating the visual function safety profile of DME therapies.

Main Results:

  • Microperimetry enables precise, fundus-related quantification of retinal sensitivity.
  • This technique offers a more accurate assessment of visual function in diabetic retinopathy.
  • Microperimetry is transforming the functional investigation of diabetic retinopathy.

Conclusions:

  • Microperimetry is a valuable tool for assessing visual function in diabetic retinopathy.
  • It provides essential data for diagnosing and monitoring DME patients.
  • This technology is advancing the functional evaluation of diabetic retinopathy and its treatments.
